Topics are the building blocks of DITA, and a methodical apporach to
topic creation will result in consistent and more effective documents.
Rather than manually creating links from parent topics to child topics, and arranging the links into a formatted table, you should take advantage of the ability to automatically generate links and descriptions to topics subordinate in the hierarchy. A parent stem topic in the DITA source can become an important introductory topic in the deliverable document.
Disambiguation topics help direct readers to the appropriate content where a term or concept is ambiguous and may refer to more than one topic.
Avoiding linking in topics
A topic with an embedded link is bound to the target of that link. If the target topic is not included in the same output, the link is not relevant (and will appear as a broken link in the output). Links should therefore be removed from the topic to the ditamap; the map being the place where context is stored.
